Malachi 2:15-16

C. Command: stop acting faithlessly 2:15b-16

This "command" section begins and ends with commands not to break faith. Instruction to "take heed to your spirit" immediately precedes each of these commands. Two quotations from Yahweh lie within this envelope structure. These commands from Yahweh constitute the turning point in this second chiastic hortatory discourse (cf. Malachi 1:10).
